KNIT FABRIC.

Application led February 5, 1925,. Serial No. 7,006.

One object of. this invention isto produce anew form of double knit. fabric, that will resemble a woven fabric, and embody. the advantages ofy being practically non-stretchable in both directions, yet can. be produced more economically, because a knitting machine has about five times the capacity. of a loom. p Y

Another object of the invention is to produce a double fabric that is interknit, yet the fabric produced can change at any time from a double fabric to. either one of twofabrics. alone, by simply omitting one or more of the threads` fed to the needles and, suitably controlling the needles and. their cooperating sinkers..

A further object. is` to produce a double knit fabric in which` one fabric will resist. stretch. or sag longitudinally,` and. the other fabric will resist stretch or. sagA transversely; whereby the knitting together of such two fabrics willi eliminate stretch. or sag in. all

directions in the fabric.. Y

Another object of this invention. is to prod'uce a new form of double lmitfabric that will show different effects or designs on the opposite sides, sothat either. side may be ex-y posed inthe article, andk also inthe article the pleat or turned edge can be used? to produce different effects. in. the article;V and. which. fabric on one face will. have the ehect of a wovenA fabric, while the opposite face..`

willhave a. different eifect,.and be very similar tothe outer face of the plain knit fabric.

upon one or more of1 thethreads being' cut f or. broken.

Another object of this inventionis to provide a. double fabric that is interknit,` and inwhich a. number of differently colored threads canl be made to. produce novel effects, and. which can be varied by. omitting one or more of the threads at certain parts of the fabric.

In the accompanyingdrawingsl showing one embodiment of. my invention, Figure lf Y showsthe finished. fabric.

Fig. 2 is af view of the rear side of the` fabric.

Figure. Sindicates in= a diagrammatic form an ordinary knit. fabric.

Figure 4f indicates the fabric with the or` dinary knit composed only ofi the float threads, omitting the plain loop thread.

Figure 5 indicates av method of knittingv my improved'` fabric shown from the outer side, but with the threads separated, the plain knit threads being indicatedby. broken lines andthe float. threads by fulllines.

Fig. 6 isa diagrammaticY view as it: would appear at an edge of'theffabric.

As shown in Figs. 3 andl, theplai'n knit of." circular or other form is produced byl a single thread, three courses being` indicated by l, 2 and 3, each forming theusual needle wales andl sinker wales. supply additional th-read's,.tl`1ree,threads, 2l, 22 and 23 being indicated,r and which separately combine with the loops in the course 1, alsoY in the similar manner i'n ythe courses in which the same. three threads. form other courses. 1n. the same manner.V

But -these three extra threadsl are not all knit in with each ofithe walev loops, but each ForY each course I.

thread is knit in. with spaced loops of. t-he forma twoQthread.' loop; thereupon floated atl?.y over the'loops 8 andi), andknit inwith the loop l()V at. 29.. In the sameemanner this thread continues to loop; over two wales, and is knitl in at the.third loop, and every third loop thereafter. .The second eXtra thread 22. does not knit i'n with the'. loop 4', hut floats over it and is knit inthe loope at 27 to. make the double Athread loop. `This thread 22 thereupon makes along float 18,

and/is `knit in. with Vthe loop 8 to form a double threadloop at 30'. Ifn'the same manner this. thread221for1'ns. a long l'oopl`19 over loops 9 andlO, i'skni't in with the nextloop,

floats over the following two loops,`andl is knit.. in with the next l'oop yin the same manner., l

The third float thread 23' is floated' over loops .Ll and 5 at 2.0,.and is knit in with the loop 6 at- Sl tofform a double thread loop. 'lhis thread 23'v then floatsat 24k over two loops 7. and: 8, is knit inwith loop 9 at 32 floats. at. 25 over two loops, and is knit in with. theneXt loop. It ywill" be-thus seen that. each oflthe loopst to,10Y have'a single one off the, threads 21 or 22,. or 23, knit in, and each of these is. alternately floated over two wales, and knitfin with the third wale; yet itwilly have but' the single eXtra threadknit in With it. The effect of such a fabric is Y that the main or outer vface is formed almost tion of the tendency to sag or stretch.

entirely of float threads, that have a length of three complete Wales in ,.Width. `On the back or reverse side the plain knit Wales show each needle Wale composed of a double thread that is Woven lrather tight. By this means is produced What is substantially a double fabric, that on the main side has the appearance of theright side or outer face of an ordinary plain knit fabric, Yet these `two fabrics are knit togetherl and each strengthens and supports the other. rlhis results in two great advantages in the fabric.

In the first place. it is practically impossibleV for the fabric to produce What is known as a run; Where a thread is cutV or broken in the present fabric, a run will start that may It has been further found that the fabric' of this kind Which uses a single thread in the Way of a plain knit, that is continued in each course, and the additional three float threads for each `course or lay of the plain knit, can have the three threads stopped,

and the plain knit continued, and then the fabric resumed With the three float threads for each course; whereby bands of plain knit are combined With bands of the new fabric, in thecontinuous knit. It has been further found that in forming such a fabric, that the plain knit can be stopped, and the three threadsknit together that willv produce the structure as indicated in Fig. 5, being composed of a plain knit loop with floats extending over two loops and knit in each third loop. Such fabric on the reverse side will Vhave single thread loops.

A fabric of this kind Will be found to ppossess the desired extra weight Without overloading with threads.

It has been found that in knitting my fabricas indicated inrFigs. l, 2 and 5, that the threads l, 2 and 3 can be omitted at any time in the course of knitting, and the Voperation continued by using three float threads which will produce the fabric indicated in Fig. 4. This Will forni a continuous knit that will merge into the other form. It is to be understood that I do not conne myself to three float threads or the exact arrangement or order of these threads but reserve the right to use any such number or arrangement as will come within the scope claimed.

What I claim is:

1. A knit fabric comprising a series of Wales each consisting of interknitted loops, the thread from a loop of one Wale being extended over at least one Wale of the same course to form a float and interknit with a loop in a Wale of the same course at least two loops distant from the first loop, the thread from a loop of the Wale in the same course next the first Wale being arranged in like manner and floated over the second loop to which the first thread is interknit whereby i each loop is crossed by a plurality of float threads, each course also having a backing thread engaging 'all of the loops of the next succeeding course.

2. A knit fabric comprising a series of wales each consistingof interknitted loops, the thread from a loop of one Wale being .extended over at least one Wale of the same course to form a floaty and interknit with a the thread from a loop of one Wale being extended over at least one Wale of the same lcourse to form a float and interknit with a loop in a Wale of the same course at least two loops distant from the first loop, the thread from a loop of thewale in the same course next the first Wale being arranged inlike manner and floated over the second loop to which the first thread is kinterknit whereby each loop is crossed by a plurality of float threads arranged in regular staggered relation, all said float threads lying 1 entirely in the same course, Vand all ofthe Wales being' formed by equal numbers of threads whereby a flat unribbed fabric is formed, each course also having a backing thread engaging all of the loops of the next succeeding course.

l. A knit fabric comprising a series of Wales each consisting of interknitted loops, the thread from a loop of one Wale being extended over at least one Wale of the same course to form a float and interknit'with a loop in a Wale of the same course at least two loops distanti from the first loop, ythe thread from a loop ofthe Wale in the saine course next the first Wale being arranged in like manner and floated over the second loop to Which the lirst thread is interlinit Whereby each loop is crossed by a plurality of loat threads arranged in regular staggered relation, all said float threads lying entirely in the same course, the number of threads in each course equalling one more than the number of Wales jumped by the float threads Whereby an equal number of threads are provided in each Wale, each course having a backing thread engaging all of the loops of the next succeeding course.

5. A knit fabric comprising a series of Wales each consisting of interknitted loops, the thread from a loop of one Wale being extended over at least one Wale of the same course to form a float and interlmit with a.

loop in a Wale of the same course at least tWo loops distant from the first loop, the thread from a loop of the Wale in the same course next the rst Wale being arranged in like manner and floated over the second loop to Which t-he first thread is interknit whereby each loop is crossed by a plurality of float threads, each course also having a backing thread engaging allof the loops of the next succeeding course, the backing thread being of a different color to the remaining threads.
